The Isle is a dinosaur survival game where every player controls an actual dinosaur, not a human character with a gun. Developed by Afterthought LLC and released into Steam Early Access on December 2, 2015, it has spent a decade building a reputation as the most punishing, realism-focused entry in the genre: hatch, grow, eat, avoid becoming someone else''s meal, and try not to lose everything in a single bad encounter.
What Is The Isle?
The Isle drops players onto a fictional prehistoric island as one of dozens of playable dinosaur species, from small pack-hunting theropods to apex predators that can end a server''s biggest reputation in one bite. There is no crafting, no building, and no human inventory screen. Growth happens in real time from a hatchling to a full adult, and death is permanent for that life, so a careless river crossing or an ambush from a larger predator can cost hours of progress. That single mechanic, permanent growth tied to permanent death, is what separates The Isle from more forgiving dinosaur games and explains both the loyalty of its community and the frustration of newcomers who lose their first few dinosaurs fast.
Evrima vs. Legacy: Which Version Should You Play?
The Isle currently exists as two separate branches on Steam. Legacy is the original build from the mid-2010s, with a larger historical roster and the older Thenyaw Island and Isle V3 maps, but Afterthought has stopped actively developing it. Evrima is the actively developed branch, an early access rebuild with new maps, revised movement and combat, and a smaller but constantly growing playable roster. Nearly all of Afterthought''s current attention, patches, and new dinosaurs go into Evrima, so anyone starting today should play Evrima rather than Legacy, despite Legacy''s longer species list.
Playable Dinosaurs in The Isle Right Now
Evrima''s roster sits at roughly 28 species as of mid-2026, with around 18 in the core playable rotation at any given time, including Tyrannosaurus, Carnotaurus, Stegosaurus, the semi-aquatic Deinosuchus, and the flying Pteranodon. Tyrannosaurus was the most recent headline addition, arriving in the public branch in patch 0.21.321 in December 2025 with a full move-set rather than a placeholder model. Afterthought has confirmed Baryonyx, Kentrosaurus, and Quetzalcoatlus for further 2026 releases, continuing the studio''s pattern of adding one meaningfully different niche, rather than another mid-size carnivore, with each major patch.
How The Isle Actually Plays
Every dinosaur in The Isle has a distinct diet, social structure, and combat kit. Herbivores like Stegosaurus rely on herd numbers and terrain for safety, while apex carnivores like Tyrannosaurus hunt largely alone and can dominate a server''s food chain once fully grown. Aging is gradual and visible, and a young dinosaur of any species is genuinely vulnerable to almost everything around it, which pushes new players toward caution rather than the shoot-first instinct common in other survival games. There is no fast travel and no safe respawn near your last location; when a dinosaur dies, that specific animal and its growth progress are gone.
Price and How to Get It
The Isle is sold on Steam as an Early Access title for $19.99 and remains PC-only, with no console release announced. It requires the Evrima branch specifically for current content; Legacy is included in the same purchase but receives essentially no new development.
People Also Ask
Is The Isle multiplayer only? Effectively yes. Solo play is technically possible on private servers, but the game is built around persistent multiplayer servers where herds, packs, and rival predators are other real players.
What dinosaurs can you play in The Isle? Roughly 28 species as of 2026 across Evrima''s roster, including Tyrannosaurus, Carnotaurus, Stegosaurus, Deinosuchus, and Pteranodon, with Baryonyx, Kentrosaurus, and Quetzalcoatlus confirmed as upcoming additions.
Is The Isle still in development? Yes. The Evrima branch is under active, frequent development; Legacy has been effectively frozen while Afterthought focuses resources on Evrima.
Is The Isle realistic? It is built around permanent growth and permanent death for each dinosaur, plus species-accurate size and diet differences, which makes it considerably less forgiving than most competitors in the genre.
Ten years into early access, The Isle''s core pitch has not changed: you are the dinosaur, the island does not care, and every life you lose was earned the hard way.
